Can someone help!
I recently completed an O2 switch up, returned my old device and then received the notification that the device was returned successfully to O2, however my bill still shows this old device on my account and I am still being charged for it! O2 stated I need to go instore to amend but they can't do anything, billing, customer services, switch up team and the contracts team cannot do a thing about it (useless) I was on a call for 2 hours trying to resolve this and O2 hung up!
I am now getting desperate can anyone help?
